c5e859dbdc GeometryCore: Add FColliderMesh::FindNearestHitTriangle() and FColliderMesh::FindNearestTriangle() wrappers around AABBTree functions. Replace most calls to these functions via AABBTree w/ calls to FColliderMesh functions. Rename ::GetAABBTree() to ::GetRawAABBTreeUnsafe() to discourage usage (intention long-term is to encapsulate the spatial data structure, so it is not exposed)

48e1cabf77 Added support for world-space hit-testing and snapping to Volume and DynamicMeshComponent mesh vertices/edges/faces, by having Modeling Mode maintain a persistent set of spatial data structures for these scene meshes. With this change, new ToolSceneQueriesUtil functions can be used to provide more general scene mesh-element hit-testing/snapping via ModelingSceneSnappingManager. Updates to existing Tools/Mechanics to use these new query functions will be done in later CLs. 
ToolsFramework:
- added new USceneSnappingManager::ExecuteSceneHitQuery API function, as well as accompanying FSceneHitQueryRequest/FSceneHitQueryResult structs
- added FSceneQueryVisibilityFilter struct which contains ComponentsToIgnore/InvisibleComponentsToInclude lists for snapping queries and provides shared IsVisible() implementation

ModelingComponents:
- add FLevelObjectsObserver, tracks Actors added/removed to a Level via various editor events
- add FSceneGeometrySpatialCache, maintains spatial data structures for known types of mesh-backed PrimitiveComponents, an octree based on their world-space bounding-boxes, and provides various spatial-query functions
- ModelingSceneSnappingManager now maintains a FSceneGeometrySpatialCache for a set of Actors/Components it is notified about, and updates the spatial cache if those components are modified or translated. Currently supports Volumes and DynamicMeshComponents.
- add ModelingSceneSnappingManager::ExecuteSceneHitQuery implementation, does raycasts into the world (for static mesh components) and FSceneGeometrySpatialCache for Volumes/DMCs
- modified ModelingSceneSnappingManager::ExecuteSceneSnapQuery to also do combined query against StaticMeshComponents via world-linetrace, and FSceneGeometrySpatialCache for Volumes/DMCs
- add ToolSceneQueriesUtil::FindNearestVisibleObjectHit variants that take a USceneSnappingManager or UInteractiveTool, and do queries via the SceneSnappingManger, instead of directly linetracing into a UWorld

ModleingToolsEditorMode:
- add FLevelObjectsObserver instance and use it to drive updates to active ModelingSceneSnappingManager
